The Importance of Cathedral Thinking

John Defterios: Dublin Port is a moving example of Cathedral thinking. He says the people who built Cologne Cathedral are Notre Dame, those people built buildings that they knew they would never see when they were completed. This week he talks about how cities take control of their environment and say what do we want this to look like? It's not in five years time or 10 years time, but in 100 years time or 200 years time - building cities takes a long, long time.
